SAB 4.7.1 Mac book Title Bar on Top screen

Could it be that SAB 4.7.1 Mac somehow places the book abbreviation of 1 and 2 Thes. in the bar on top of the screen instead of the full book title? We see it happen only in this epistles and not in any other book and we cannot find an explanation so far … we keep checking but in case you find it is bug, please let us know!

Is the app online for us to look at?

yes

SAB 5.0 now … I find that SAB or the APP or both “decide” when the the title is too long, to use instead the abbreviation that you enter in SAB. I cannot find any explanation of that ‘rule’ but it will be related to the number of characters that ones uses? Does anyone know how many is the limit?
